Re: Excelerator plus pcb repair warning

I'm pretty glad I found a 74LS133 DIP here in Montreal. It was the only 74 family chip I didn't have in my crap. You should've asked me.

Re: SaRuMan-TED 64k RAM for C16 and C116

Re: 1541C unusual "Shorter Board" version - J3?

Very interesting! This suggests that a preventative fix might be possible if the write current can be reduced while maintaining performance. For now, I suppose, I'll be sure to use my Alps drives as destination disks for making copies. On boards 250442 & 250446, the jumper configuration suggested f...
